INKING-ROLLER TRUCK.

Application filed December 11, 1922.- Serial No. 606,227.

To all whom it may concern:

Be it known that I, HERBERT G. LA Son, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Inking-Roller Truck, of which the following is a specification. I

This invention relates to an inking-roller truck, such as used in printing presses for inking the faces of the type set up in a form. In the operation of such inking rollers, they are guided over the type by means of guide-rollers. which run on guides, or guide-rails located at each side of the form. The diameter of the inking roller is subject to variation for different reasons and under some circumstances the roller may pass too close to the type or too far from the face of the type, thereby producing imperfect type impressions on the printed sheet. a

The general object of the present invention is to produce simple means for overcoming this difiiculty and to provide a simple construction of inking roller truck, which will enable the position of the inking roller to be slightly altered at will, to

the end that it will operate effectively in the inking process; also to provide means whereby the alinement of the roller, as suggested, can be accomplished in such a way that after the adaptation or new alinement of the roller has been effected, it will be held positively in a predetermined relation, with respect to the face of the type, that is to say, I avoid the dependence upona gradually adjusted. part and produce a predetermined adjustment, by merely reversing the roller on its shaft.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combination of parts to be described hereinafter, all of which. contribute to produce an efficient inking roller truck;

A preferred embodiment of the invention is described in the following specification, while the broad scope of the invention is pointed out in the appended claims.

In the drawing:

Fig. 1 is a front elevation. showing a portion of an inking roller and indicating the guide rail and a portion of the type; supposed to be set up in the form; and also showing the adjacent guide roller, which supports the inking roller.

Fig. 2 is a view similar to Fig. l, but showing the guide roller in a reversed position, soas to effect analteration in the alinement of the inking'roller with respect to the type faces.

Fig. 3 is an end elevation of the roller roll along on a pair of oppositely disposed guides or guide rails 4, fixed at each side of the printing press, in such a way that when on taken on the line.

the inking truck passes over the faces of the type A, set up in a type form, theink will be transferred from the roller to the faces of the type. v

With such a construction, a very slight variation in the diameter of the inking roller 1, or the guide roller 3, may produce imperfect transference of the ink to the type. It has been attempted to overcome this difficulty byproviding for an adjustment of the diameter of the guideroller, and this methodinvolves a gradual increaseor decrease in the diameter of the guide roller, the result of which isthat constant .readjusting is necessary. It also frequently happens that a printing job" may involve the use of a number of inkingrules, set up in the form, which have a tendency to cut or score the face of the inking roller.- Under such circumstances my invention enables the inking roller to be raised slightly and alined in a slightly removed position; the amount of removal will be a predetermined amount, which is constant for the press.

iiccording to my invention, 1 coi'istruct, the guide roller 3 withtwo roller parts, 3"- and 3 which are preferably made of two distinct pieces, one being of slightly larger diameter than the other. This roller 3 is secured to the shaft 2, which projects over or adjacent to the guide' rail 4, by "means that will enable the roller to be secured to the shaft 2 in one position, in which the roller part 3 will roll on the face of the guide rail, and ,in a reversed position in which the roller part 3* will roll on the rail.

In order to accomplish this, the roller '3 llO rims rolling on the rail and in a reverse position Witlltlle other rim rolling on the rail, said rims having a circumferential groove formed at their adjacent faces to produce a gap between the bearing faces of the rims whereby when one of the rims is resting on the rail the other rim is held away from the rail and out of contact With the same.

4. In an inking roller truck for inking type, the combination of a track rail for guiding the truck, an inkingroller having its shaft disposed adjacent to the rail, a guide roller having a metallic hub mounted on the shaft and having tWo rims of a relatlVQly hard and slightly compressible material mounted on the hub, means for clamping the rims on the hub, said hub and shaft cooperating to enable the guide roller to be applied in one position With one of the rims.

rolling on the rail and in a reverse position with the other rimi rolling on the rail, said clamping means including a clamping collar having a threaded connection With the hub and having recesses formed in the edge thereof, operating when the rims are clamped, to compress the material in the rims, the material of the rim under the recesses operating to prevent the unscrewing of the clamping Washer.

Signed at Los Angeles, California, this 4 day of December, 1922.
